Application filed. June 7,

To all whom it may concern:

, a citizen of the United States, residing at the borough of Manhattan,in the city, county, and State of New York, have invented certain newand useful Improvements in (linematographic Targets, of which thefollowing is a specification, reference being had therein to theaccompanying drawings, which form a part thereof.

My invention relates to cinematographic targets and more particularly tothe back plate. and web feeding structure and the mechanisms appurtenantthereto for securing accuracy in marking the effectiveness of the fire.

In cinematographic targets of the type to which my invention relates,the essential characteristics thereof are a movable Web of paper orother frangible, opaque material extending and having movement acrossthe frame of the target, and forming the screen upon which the movingimage is projected and against which fire is directed. Rearwardly ofthis screen is one, or a plurality of movable back plates adapted toreceive the force of the impact of a bullet passing through the screenand to have movement thereunder, so as to either make or break anelectrical circuit each time a bullet strikes the target, and thus setin motion certain othc mechanisms in the machine which will have theeffect of stopping the projector so as to convert the moving image to astill image and permit light rays to pass through the openings in theweb formed by the bullet for a sufiicient interval to permit the markerto determine the accuracy of the fire.

Heretofore there have been used three distin-ct types of machines so faras the paper web is concerned, in one of whi h a single reach of web isused, the breaks therein being closed by hand; in another of which twoparallel reaches are used so that with the actuation of the web feedingmechanism, the two reaches have movement in opposite d1- rections so asto cause each reach to closethe 1919f Serial no. acacia.

opening made by the bullet in the other, the feeding of the web in thstype being intermittent, and either manually or mechanically effected;and in the third of which the web is fed continuously at a very lowspeed to impart movement to the two parallel reaches thereof and thusobscure the openings.

Where the back plate structure embodies a plurality of independentlymovable plates, it has heretofore been the common practice to provide amake and break mechanism as sociated with each plate, thus leading to asomewhat complex wiring of the apparatus with a proportionate increasein the possibilities for disarrangement of the circuits and a resultantfailure of the target to properly function.

My invention relates more particularly to a type of target in which theweb is continuously fed at low speed, the construction of the target andthe feeding mechanism for the Web being such that the speed of travel ofthe web may be very much reduced while securing an effective closure ofthe bullet openings through the various reaches of the web, thusminimizing likelihood of inaccuracy in the marking due to the holesexisting in one reach registering with holes in other reaches. Byreducing the speed of travel of the web, I secure economy as to theconsumption th reof during given time.

The web feeding mechanism is so constructed that the used web will berewound upon a reel with the ragged edges of the openings formed by thebullets so smoothed out as to permit the formation of a neat rollthereof, the power acting upon the rewind reel being so applied theretoas to ensure uniformity in the speed of travel of the web, irrespectiveof the varying diameter of this reel.

In addition to utilizing the movement of the 'diii'erent reaches of theweb for cl scuring the bullet openings therethrough, I provide meanswhereby difierent reaches of. the web will have movement with relationto I each other independentof the traverse thereof imparted by thefeeding mechanism, thus increasing the efiectiveness of these reaches inobscuring such openings.

The light from which the rays passing through the registering bulletopenings emanate, is so arranged passing through the machine, that aportion of this web will act as a reflector, thus se-' vention, is soconstructed and arranged as to function continuously Without likelihoodof its registering a hit except where a bullet passes through thescreen, and of the various mechanisms therein becoming disarranged orbeing injured by the bullets di-- rected against same. 7

The invention consists in the novel features of. construction andcombination oi parts'hereinafter set forth and described,

and more particularly pointed out in "the claims hereto appended.

Like letters refer to like parts throughout the several views. Intheembodiment of'my invention shown in the drawings. the main frame ofthemachine 1, which is preferably made of metal,

has,at the front thereof, an ordinary frame.

with relation to the web 2 within the sight opening of which the imageis to be projected. The rearu'prights of the frame are inclined, asshown, for the purpose of facilitating the mounting of the 7 back platesin a manner which will be'hereinafter described.

Below the frame.2,, upon opposite sides of themachine,'1 providesuitable bearings 3 for a reel having thereona roll 4 of web V offrangible, opaque material such as paper,

The web from the roll 4 passesv about a guide roller 5 adjacent thebottom of the machine, then upwardly across and'within the sight openingof the frame 2, over and about the guide roller 6 at the top of themachine, and about the guide roller 7 adjacent thereto, to the guideroller 8 adjacent and below the roller 5, around and about which itpasses, the third reach thereofpass 'ing about the guide rollers 9 and10 'adjacent the bottom and the top of the machine respectively, thusforming three closely juxtaposed, parallel'reaches 11, 12 and 13 withinand extending across the sight open ing of the said frame 2. Of thesereaches the front one, 11,. forms the screen against which the image isprojected. By this con- 7 struction' the bullet in passing through the fweb makes three registering openings, the passage of light through whichwill indicate to the marker the-accuracy of the fire. V

The web is ofa width greater than that of the sight opening in the frame2, so that the bullets directed at the screen will not mutilate theedges of the web which, re-

maining intact, will always afford sufficient strength of material toensure the desired feeding movement of the web;

After leaving the guide roller 10, the web passes to a rewind-ing reel14. being guided 1n its course by the guide rollers 15, 16

and 17,;the roller 17 being'arran'ged forwardly of the roller 16, so asto provide a downwardly and forwardly inclined reach 18 extending towardthe bottom of the frame 2. V 7 a The rew nd reel 14 is continuouslydriven irom'the motor 19th'rough a suitable speed reducingmechanism, bya mechanism which will be hereinafter described, the construction andarrangement ofv which, however, is

such as to impart acontinuing lineal traverse to the web throughthe.machine, at.

uniform speed, the rate of travel, in the form of the invention shown,being a'pproxi- 'mately seven feet per hour.

At the top of the machine, 15 and between the reaches l3 and 18 oftheweb, I mount'alamp or lamps 20 provided with a suitabl'e'reflector 21 soas to direct the rays therefrom downwardly against the reach 18, whichwill thus serve to reflect and diffuse the light in a manner to properlyilluminate the space rearwardly of. said reach l3, so that light rayswill pass through below. the roller iii registering openings made by abullet in any part of the reaches 11, 12 and 13, Within the si htopening of the frame 2.

The pulley 22 through which power is applied tothe rewinding reel, isearned by the shaft of a roller 23 extending transversely of the machineand having associated tlvrewith, and spaced away therefrom, secondroller 241- which may be either geared theretoor idly mounted. Therollers 23 and are so spaced apart as to form a seat for the rewind reel1 1, which reel is adapted to be frictionally driven by engagement withsaid roller or the rollers 23 and 2 1. In this manner, irrespective ofthe diameter of the said reel 1 1, it will al' ways be driven at thesame peripheral speed, thus ensuring uniformity in the speed of traverseof the web -l-, through the machine.

To ensure the desired frictional engagement between. the reel 14 and therollers 23 and 2%, I provide various devices exerting a constantpressure upon the reel 14;, these devices being so arranged toaccommodate themselves to the gradual increase in diameter of said reel14%. in addition to developing this pressure, these devices confine thesaid reel in its position adjacent to the rollers 23 and 2st, thusfacilitating the removal of the reel when it has attained the maximumsize desired and the substitution of a fresh reel therefor.

The pressure developed by these devices will also tend to smooth theragged edges about the holes made in the web and thus cause it to windmore or less compactly upon the reel 14.

One of these devices consists of aroller 25 mounted upon links 26pivotally connected with the levers 27, which are in turn pivotallyconnected with the frame of the machine. The roller 25 bears upon oneside of the reel 14 and imparts a thrust thereon toward the roller 2%.Above the rollers 23 and 2a: is a roller 28 mounted in the arms 29pivotally supported from the frame of the machine. Passing about therollers 24 and 2S and about the roller 30, is an endless belt 31 whichconforms to the roller upon the reel 14 and is driven therefrom, or ifdesired, from the roller 241. To compensate for the increasing diameterof the roller upon the reel 14;, the roller 30 is mounted upon pivotedarms 32.

The link 26, the lever 29 and the arm 32 are acted upon by the weight 33by means of the cords or ropes 34. 35 and 36, the first of which passesabout the pulley 3'T and is connected to the lever 29, the second ofwhich is connected directly with the link 26,

and the last of which is connected directly with the lever 32. The rope35 is connected directly with the weight 33, the ropes 3 1 and 36 beingreaches of a continuous strand connected with said weight 33 by means ofthe pulley 33 about which said strand passes. This construction permitscompensation for any difierence in the quantity of movement of the leverarms 29 and 32. By this construction the stresses from the weight 33 aredistributed about and applied to different portions of the roll whilepermitting the rollers 25 and 28 and the belt 31 to automatically adjustthemselves to the constantly varying diameter of the roll upon the reel14.

By thus employing three parallel reaches of the web at the sight openingof the frame 2, and imparting continuous lineal traverse thereto, two ofthese reaches will have simultaneous movement in the same direction,While the other will have simultaneous movement in the oppositedirection. While this condition will have a tendency to ra idly obscurethe bullet openings in the screen, or bring the openings in the threereaches rapidly out of register, there is always likelihood, howeverinfrequent, of existing openings in these reaches, registering with eachother at, a point other than that through which a bullet passes, so asto cause a false indication of a hit.

To minimize likelihood of this condition arising, I provide meanswhereby in spite of uniformity in the rate of takeup of the web, thereaches 11 and 12 will have relative variable movement, thus constantlyincreasing or decreasing the movement of one of these reaches withrelation to the other.

To secure this result, I mount the guide rollers 6 and 8 upon verticallyreciprocatory distance rods 38, which rods are alternately raised andlowered by a mechanism deriving its power from the shaft of the roller23. By this construction, as the rods 38 are raised, the rate of travelof the reach 12 will be decreased as compared with that of the reach 13and as compared with the relative speed of the reach 11, slack in theweb thus created adjacent the guide roller 8 permitting continunity inthe operation of the takeup mechanism or reel let. With the downwardmovement of the rods 38, the rate of travel of the guide 12 will beincreased, the slack created adjacent the guide roller 6 compensatingfor this increased rate of movement of the reach 12, the rate ofmovement of said reach 12 being, during this interval, relativelygreater than that of the reach 11. The rate of traverse of the reach 11will be the same as that of the reach 13, as well as being in the samedirection. Under the above conditions, the length of the reach 13, witheach downward movement of the rollers 6 and 8, will be increased to anextent commensurate with the length of movement of said rollers, whilethe length of the reach 11 will be correspondingly decreased. The lengthof the reach 12 will remain constant. The relative variance in the s eedor" travel of the reach 12 with relation to the ment of the roller 23into a reciprocatory-y reaches 11 and 13 will have the efteetofminimizing any tendency of old openings iirthe different reaches of websbeinglnought into register in a manner to cause false marking of theeffect of the shock. V

In securing the desired results, I a mechanism for imparting movement tothe rods 38 which will convert the rotary move movement, without anysubstantial variance in the. speed or said "rods, or without: any deadcenters or intervalsot' rest when changing; the tlon of movement of therods.

This mechanism comprises a bell crank lever 39 associated with each ofthe rods 38, one'arm of each which isoperativcl; connected th rein tocompensate tor the arc described thereby. Th other arm oi? said lever ispi\-*otally connected with a pitman 40. having pivotally connectedtherei with oppositely disposed hooks ll; and. 42. upon by: thethe heelsof which are acted spring" 4E3. Carried by the shaft oi the roller 23are four studs, (1, Z), and (1' arrangedQO" apart on a circle concentricwith the'axis of said shaft, the studs a and .4 being-adapted toco-operate with the-hook -i-l im 'iarting movement to the pitman 4C0,while the studs Z) and a. cooperate with the hook i2 imparting movementto saidpitman in the opposite direction. 'he hook ll is provided with abevel as with which the studs Z) and dco-operatc in disconnecting thehook all from its co-operating power applying stud at. the limit of theoperative movement of the stud thereon. the hook being provided withsimilar beve lfiwith which the studs a andc cooperate with a The hook412 is provided with a similar slot upon a parallel plane, adapted toreceive the arm carrying the studs 7) and (Z. and thus permitting bothof these studs to engagesaid hook. Since the slots. which are learlyshown in Fig. 9, are upon diil'erent planes,

it follows that'the ends ofjthe arn r carrying the studs Z) and (Z willprevent engagement of the hook 4:1 with either of said studs, since itwill engage the face of said hook at one side of said recess. Thesamecondition prevails in connection with the hook 42 and the armcarrying the studs a and c.v

In Figs. 5 to 8, I have illustrated the four difi'erentoperativepositions of thismecha nism, Fig. 5 illustratingthe' relationof parts at the interval, of the disconnection ofthe 11001: ll from thestud a and the connection of the hook 42 with the stud I), this bein theposition when the rods 38 have reached employ their uppermost position.bWiththe con} tinued rotation of the studs, the pitmau to maintain thedesired engagement withthe stud Z). lVith this movement the arm dsupporting the stud cZ willengage the hook ell until the stud passes tothe position shown in Fig. 7; at which interval the stud a will engagethe bevel upon the hook thus disengaging saidhook'iromthe stud Z2. Atthe same time the hook ll will engage the stud c and thus reverse themovement of the pitman, the arm. d supporting the stud a preventing saidstud from operatively engaging the hook during this interval.

By this construction l. secure about seventy per cent of the effectivethrow of the rotating member and avoid any substantial slowing-down andno dead centers in the operation of the pitman; thus e nsuring a prickreversal in the direction of movement of the rods 38 and acompleteelimination oi a possibility of the failure of he variable speed otthereaches 11 and 12 atany time when a bullet happens to strike same.

Carried by the inclined uprightsat the back or the frame 1, are aplurality of groups 019 back plates, the adjacent plates or each groupoverlappingeach other upon a horizontal] plane and overlapping theplates of the adjacent group upon a ver- :ticakpla-ne so as to alford'nodeadispaces about the plates and thus ensure the actuation of this backplate,mechanismwith the impact of every bullet therewith. V

The construction and arrangement oteach plate is similar to every other,and-a description of but one of tliem'istlierefore necessary. Eachgroupofback plates is composed of a plurality of pendulous metal platesl6 pivotally supportedby means of the rods 47. bell crank lever 4-8, onearm of which is connected back plate.

Back of each plate 46 is a 110 by a link 4-9 with its cooperatingAdjacent thetop of eachgroup of back plates to is a walking. beam 50,one arinof' which hassuspended tljreretrom a weight 51 while theotherarm thereo'lis pivotally eonnectcd with a reciprocatory switch actuating'rod 52slidably mounted in suit-ablefbearings in the trame Said rod hasthereon a plurality of blocks 53 arranged one. adjativelyengaged by onearm thereof so that 7120 cent each lever lSin' positionto be operathe'rod 52 may be actuatedto control the back plate circuit. by every plateotthe group with which it is associated; Preferablythe various blocks 53vare adjustably mounted'upon the rod 52 to permit all of said blocks tobe similarly positioned; in re v lation to its co-operating lever. 7

Below and within the operative range of each rod 52 is a make and breakmechanism consisting of the opposed electrical contacts 1: and 55, one01"- which as 54 18 a sprmg contact which the rod 52 engages when.de-energizes the magnet of a relay 56, thus closing a secondary circuitto a solenoid 57 which actuates through mechanical connections, theprojector stop device and other mechanisms about the machine. Arranged ashunt circuit from the secondary circuit is a timing device 58, whichalso includes therein the relay 56. also employ a rotary switch 59actuated in synchronism with the projector, and arranged in the primarycircuit so as to time the tie-energizing of the solenoid with relationto the feeding of the film. V

To protect the various mechanisms in and about the back plate structurefrom the splash of the bullets directed against the various back plates46, I provide each of said plates with a shield 60 extending from.

the top tl ereof towards and in close juxtaposition to and below a crossrib 61 upon the adjacent upper plate of the same group,

the shield on the uppermost plate 16 projecting into'close proximity tothe reach 18. These shields may be of light sheet metal since they arerequired to withstand only a glancing impact of spent bullets orfragments thereof. The reach 18 will also serve to protect the reaches11, 12 and 13 from the. splash of the bullets.

Beloweach reflector 21, I provide a light permeable screen 62 which willprotect it and the lamp from the splash of the bullets.

Above the rewind mechanism and below the various groups of back platesis a salvage pan 68 adapted to receive the bullets as they drop afterimpact with the said back plates.

The operation of the herein described target structure is substantiallyas follows While the target is in operation the primary circuit to therelay 56 is closed, the rotary switch 59 being connected in multiplewith the contacts 54-55, ensuring continuity in the flow of the currentto said relay until a picture is properly framed.

The web from the roll 4 will be continuously fed through the machine bythe rewind mechanism actuated from the roller 28, thus permitting, ifdesired, the entire exhaustion of the supply of the web upon the roll 4before stopping the machine.'- The impossibility of rewinding the web,however, in as compact form as in the original roll, by reason of theragged tears therein, makes it desirable to remove the reel 14: whenonly a portion of the web has been rewound thereon, in order to avoidexcessive bulk in the waste paper rolls.

While the web is moving through the ma chine, the reaches 11 and 13 willbe moving upwardly, while the intermediate reach 12 will be movingdownwardly, thus ensuring a rapid closure of openings made by the bulletthrough the three reaches, the variable speed of the intermediate reach12 with re lation to the reaches 11 and 13, heretofore described indetail, ensuring a constant change in the relation of said reaches, soas to ensure the closing of these openings and prevent the accidentalregistering of openings made in said reaches by different bullets.

While the electrical conditions are as above described, the projectorwill be 0perative to direct a moving image upon the screen.

l hen fire is directed against this image, the bullet will pass throughthe reaches 11, 12 and 13, thus permitting light emanating from the lamp20 and reflected from the reach 18 to be visible from the front of thetarget and permit accuracy in the marking of the fire.

Substantially simultaneously with the passage of the bullet through thescreen reaches, it will impact with some pendulous plate 46, the forceof the impact, even with a small caliber, low power projectile beingsufficient to force the back plate 46 rearwardly. This causes the link49 of said plate to actuate the bell crank lever l8 associatedtherewith, to force the rod 52 downwardly, thus momentarily opening theprimary circuit and closing the secondary circuit to the solenoid 57,the actuation of which will instantly stop the projector and convert themoving image to a still image, before the movement of the web has beensufficient to close the registering openings in the screen reaches.

Vfhile the back plate 46 will immediately return to normal, thus againcausing the contacts 54 and 55 to rcengage, this movement will not closethe primary circuit, since this can be done only through the relay 56,the reenergizing of which is by said secondary circuit which iscontrolled by the timer 58 arranged in the shunt circuit of saidsecondary circuit. The actuation of the timer, however, will, after apredetermined interval coincident with or subsequent to the closing ofthe registering bullet openings through the screen reaches, close thesecondary circuit to the relay, thus restoring the electrical conditionsand restarting the projector.

This operation or the back plate mechanism in controlling theprojectorwould be the same, irrespective of what back plate a bullet may strike,the back plate of each group acting similarly upon the rod 52 bulletopenings made through the screen,

since with rapidly succeeding shots the inertia of parts is sutlicientlygreat to make an intermittent feeding movement of the web impracticableand unsatisfactory.

1n a tar et constructed in accordance with 7 my invention, the variousparts are so constructed and arranged that the target may be operatedcontinuously without likelihood of any such disarrangement of parts aswill "necessitate even a temporary shut-down.

The various mechanisms are so protected from the spent bullets or fromfragments thereof, that they cannot become clogged.

.It is not my intention to limit the invention to the precise details ofconstruction shown in theaccompanying drawings, itbeing apparent thatsuch may be varied without'departing from the spirit and scope of theinvention.
